It is very likely that you will become annoyed when you see a Server not found error when you open a website on Mozilla Firefox.

What causes the “Server not found” error in Firefox?

So that I can resolve the issues myself, I would like to have Firefox error messages changed.
Weak Internet connection: Another reason that can cause the “Server not found” error can be a weak or unstable Internet connection. A good quality Internet connection is necessary to establish a reliable and stable connection.
Problems Connecting To Server
When you ping the server from your computer, you will be able to determine whether everything is working properly.
Cannot Connect To The Server
Just restart your router from your end. You can resolve most connectivity problems by disconnecting your router for 30 seconds and reconnecting it to its power source after that. After that, you need to wait one minute for it to complete starting up.
Check if the problem is isolated to Firefox if you receive a Server Not Found error in Firefox. Try using Internet Explorer or Safari on a PC to see if you receive the same error. Firefox is the only browser that has this problem, so the problem is likely to be related to settings. If you are having trouble connecting to your network, click the Firefox button, select the “Advanced” panel, click “Network” and click “Settings.” Make sure the proxy setting is set to “No Proxy.”
The proxy server itself may be down, disrupting your Internet access. Try connecting without it if you use a proxy server to connect to the Web. In Firefox, click “Preferences,” then select “Advanced,” to deactivate the proxy server. In the Connection Settings and Preferences windows, choose “No Proxy” and close the windows. Test the connection by clicking the “Network” tab and “Settings.”
A technical fault on the server-side: The main reason for this error may be a technical fault on the server-side that prevents the user to establish a connection between the browser and the website, causing the browser to display a “Server not found” error.
Not Found On This Server
Ensure your computer is connected (wifi, router, etc.) before you enter a URL and you will no longer receive the server-cannot-be-found message.
Problem With The Server
Several variables can cause a server to go down. A physical machine might lose power, the operating system might have an issue, or maybe the network card has an issue. Managing a lot of servers and websites can be very challenging if you’re an IT professional.
Blocked Site: The user may be attempting to access a site that has been blocked by the local government for security or privacy reasons. Attempting to access a blocked site may cause an error and the user will see a “Server not found” error instead of the site’s home page.
